Can Interactive Finite Element Analysis Improve the Learning of Mechanical Behavior of Materials? A Case Study

ABSTRACT

The paper describes an interactive Finite Elements Analysis (FEA) tool that aims to improve the learning of mechanical behavior of materials in industrial engineering schools. We implemented a “user in the loop” approach where students can explore the mechanical behavior of virtual specimens selected from a library of standard elements (cantilever beam, IPE beams etc.). The users can apply forces or displacements interactively by mouse or haptic device, and visualize and “feel” the structures stress configurations. We extended our previous work and compared this novel approach with respect to traditional FEA learning techniques. A test with twenty engineering students showed that learners following the interactive approach are faster in completing the given assignment showing a reduced error rate.
